The application relates to a composite type corrosion and scale inhibition water treatment agent, which is obtained by in-situ copolymerization of phosphono carboxylic acid copolymer after modification of nitrogen-doped carbon quantum dots on the surface of attapulgite as a carrier. The application has the beneficial effects that: the attapulgite is used as the carrier, can be used as a grafting bridge to load the carbon quantum dots on the surface and in-situ generate the phosphono carboxylic acid copolymer, and has a synergistic effect; the nitrogen-doped carbon quantum dots have rich amino, carboxyl and hydroxyl functional groups on the surface, make it difficult for calcium carbonate microcrystals to gather or interfere with the normal growth of the crystals to inhibit scale crystal generation, have high stability, are coated with zinc ions, improve the antibacterial property of the material, are modified on the surface of the attapulgite, have excellent adsorption performance, and can effectively remove organic matters, heavy metals and the like in water; the phosphono carboxylic acid copolymer is in-situ generated on the surface of the attapulgite, has a good compounding effect, has a good effect on corrosion inhibition, and has good corrosion inhibition performance.

The utility model discloses a sintering sagger for lithium iron phosphate, which comprises a sagger main body, the sagger main body comprises a bottom plate and a side plate fixedly connected with the bottom plate, the bottom plate and the side plate form a containing cavity for containing materials, the sintering sagger further comprises a partition plate and a cover plate, the partition plate divides the containing cavity into at least two independent cavities, and the cover plate is arranged in the containing cavity. The top face of the partition plate is lower than the top faces of the side plates, and the cover plate covers the partition plate and is located in the containing cavity. A first limiting structure is arranged on the peripheral wall of the cover plate, and a second limiting structure matched with the first limiting structure is arranged on the inner wall face of the side plate. By arranging the partition plate and the cover plate in the accommodating cavity of the sagger main body, the carbon content distribution of the inner surface layer of the sagger is adjusted, so that lithium iron phosphate in the sagger is more uniformly mixed with carbon in the sintering process, the compounding effect of lithium iron phosphate with different sizes of particles is good, and the situation that the prepared lithium iron phosphate material is different in morphology and pole matching is avoided; the physical property of the lithium iron phosphate is influenced.

The invention relates to the technical field of microorganisms, and discloses propylene glycol eating lactobacillus and application thereof in a combined leavening agent and koumiss, the propylene glycol eating lactobacillus MNJ-2 is preserved in the China General Microbiological Culture Collection Center (CGMCC), the preservation number is CGMCC No.35857, the preservation number is CGMCC No.35857, and the preservation number is CGMCC No.35857. The invention relates to a lactobacillus plantarum strain, which has good acid resistance, cholate resistance and intestinal epithelial cell adhesion capacity, shows the potential of serving as a probiotic and has no obvious antagonism with other strains, and further relates to a leavening agent prepared by combining the strain with lactobacillus plantarum ZKLp l 800, lactobacillus paracasei ZKL200 and saccharomyces cerevisiae ZKM011 in proportion. Compared with traditional koumiss, the koumiss produced by applying the combined leavening agent is more stable in state, richer in fragrance and richer in taste, meanwhile, the traditional sour taste and wine fragrance are reserved, and the koumiss has wide application prospects in the aspect of industrial production.

This invention belongs to the technical field of sealant adhesive materials, specifically relating to a weather-resistant modified silane sealant and its preparation method. The preparation method of the weather-resistant modified silane sealant of this invention includes the following steps: S1, polypropylene glycol is sequentially subjected to alkoxide treatment and allylation treatment to obtain a polyether containing double bonds; the polyether containing double bonds and mercaptopropyltrimethoxysilane are used as raw materials for end-capping modification to obtain a silane-modified polyether material; S2, the silane-modified polyether material, filler, and plasticizer are mixed and vacuum stirred to obtain a mixture; S3, after cooling, a silane coupling agent, vinyltrimethoxysilane, catalyst, ultraviolet absorber, light stabilizer, and antioxidant are added to the mixture and stirred; the mixture is then discharged and sealed to obtain the weather-resistant modified silane sealant. This invention effectively improves the tensile strength of the material while ensuring good weather resistance of the sealant.
